21 Claims.

The present invention relates to a high chair and in particular to a convertible high chair.

Convertible high chairs are known which permit separation of the chair from the supporting structure which is designed as table, walker or the like. Yet the known constructions show several drawbacks as for instance lack of sufiiciently rigid connection between the chair and the supporting structure rendering dissatisfactory safety for the child using the chair, support of the bottom part of the chair on the table top which likely results in damage of its surface, and a number of others.

The present invention relates to new and useful improvements in a convertible high chair and one of its objects is to provide a convertible high chair, having a chair and a supporting structure, in which the chair is removably, but rigidly and securely inserted in the supporting structure.

It is another object of the present invention to provide a chair the bottom portion of which may slide into complementary means of the supporting structure for the chair, the supporting structure forming a table, a baby carriage, a walker, and a stroller, respectively.

It is still another object of the present invention to provide a convertible high chair, the bottom part of which comprises two parallel horizontal arms and the supporting structure of which has adjacent its top two guides receiving the parallel arms.

It is yet another object of the present invention to provide a convertible high chair, the bottom part of which comprises two parallel horizontal arms and the supporting structure of which has adjacent its top two guides receivin the parallel arms and means for locking the arms in the guides when in inserted position.

With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawing in which:

Figure 1 is a front perspective view of the chair;

Fig. 2 is a front perspective view of the supporting structure for the chair as shown by example in form of a table;

Fig. 3 is a side elevation of the combined chair and supporting structure partly in section along the lines 3-3 of Fig. 4;

Fig. 4 is a rear elevation of the chair combination;

Fig. 5 is a fragmentary rear elevation of a variation in the supporting structure; and

Fig. 6 is a fragmentary section of the locking means along the lines 6-6 of Fig. 3.

Referring now to the accompanying drawing, the convertible chair comprises a chair I and a supporting structure which by example is shown as a table 2, the chair being adapted to be removably inserted in complementary structure in the table 2.

While the chair I may be of any convenient design, the chair as shown in the drawing is of the conventional chair design. It is, however, essential that the bottom of the chair is equipped with two parallel horizontal arms 3 or legs which form the connection means with the supporting structure 2.

The arms 3 are each shown in the drawing as one leg portion of two preferably parallel, tubular U-members 4 and in order to render the construction more rigid the rear ends of the arms 3 are connected by a special connecting bar 5. The chair I comprises a seat 6 and back and the other leg portion 6 of each U-member I is secured to the bottom face of the seat 6 by screws (not shown) or in any other convenient manner.

The supporting structure for the chair I is shown by example as table 2 and in the embodiment disclosed in Figs. 2 to 4, the table comprises preferably two inverted substantially U-shaped members 9 the leg portions ID of which form the legs of the table 2. Two parallel bars H are secured to the U-shaped members 9 adjacent the bases 12 of the U's by welding or any other means and, thereby, form a unit in which the two U-shaped members are secured in predetermined spaced relation in approximately parallel arrangement.

Two guides i3 of preferably U-shaped cross section are supported by and secured to the bars H at an angle of substantially by welding or by any other convenient means in such manner that the openings of the Us of the two guides B3 are disposed opposite each other, thus providing an opening in each of the guides in sideward and inward direction. In addition the guides l3 may also be secured by proper means as for instance welding to the bases I! of the U-members 9. In the embodiment shown in Fig. 4 the tops of the guides l3 and the tops of the bases I? of the U-members 9 are in the same horizontal plane. A table top it is supported by and secured to the bases I2 of the U-members 9 by screws (not shown) or any other conventional means.

The embodiment of the supporting table structure, as shown in Fig. 5, has a slight variation by lowering somewhat the guides l3 and inserting face of the base I2.

the chair I in the guides 13. Such means as shown in Fig. 6 may comprise at least one spring supported bolt is provided on each guide ii. The bolt .ll penetrates the base I! of the U-member J in horizontal direction and the inner end of the bolt II is adapted to be received by a hole It provided in the arm 3 of the chair I. A spring I! is inserted into a proper inner opening is of the base I? and one end of the spring H is inserted into a small recessJS of the bolt i1 whereas its other end abuts the opposite inner bolt l1 tends to take the innermost position, that means its inner end will be in the path of the arm 3. When the arm 3 slides into the guide It the bolt i1 is pressed out compressing the spring I! and when the arm 3 reaches the position in which the hole It of the arm 3 lies opposite the inner end of the bolt IS, the latter is pressed by spring i'l into the arm 3 at the same time stopping any further movement of the arm 3. The withdrawal of the arms 3 and thereby of the chair I can only be achieved after withdrawing the bolts IS on both sides from the arms 3, thus permitting a forward sliding of the arm 3 and thereby of the chair i.

While the invention has been disclosed in connection with a table 2 forming the supporting structure, it is to be understood that any other supporting structure may be provided as long as the supporting structure has the guides i3 receiving the arms 3. Such guides may be provided on the gear of a baby carriage, of a stroller, of a walker or any other structure used for children. If used with a baby carriage or stroller, the arrangement renders the possibility of removing the chair from the carriage and using the chair as seat for the child in an automobile. while the sear carrying the guides 13 may be put in the trunk space of the car.

While I have disclosed two embodiments of the present invention, it is to be understood that these embodiments are given by example only and not in any limiting sense, the scope of the invention being determined by the objects and the claims.
